Between 1913 and 1915, Sargent made full use of his one-third-scale model while designing and redesigning architectural details for the vaulted ceiling. In 1915 several pieces were photographed in his studio. In a section of the east wall of the model one can see Sargent’s original design. Later, as can be seen in the Library murals, Sargent changed the molding on the ceiling vault, removed the inscription above Church, and added decorative borders to the two blank panels on either side.
